The Ohio Players chose to record and mix some of their albums at Paragon Recording Studios in Chicago because of how great the bass sounded there. They worked with longtime Styx producer/engineer Barry Mraz as their recording engineer. I play this one often.Good surround mix. My DTS discs have been good about presenting 5.1 without the bass sounding thin, or the mix sounding too foreign to what I was expecting, given my experience with the conventional stereo. The disc has an internal song labeling error, swapping "Love Rollercoaster" and "Let's Love".
